Two people pull on ropes tied to a trolley, each applying 44N of force. The angle the ropes form with each other is 39.5. What is the magnitude of the net force exerted on the trolley?
Two large circular metal plates are parallel and nearly touching, only 4 mm apart. The two plates are connected to the opposite terminals of a 12.0 V battery. (a) What is the average electric field strength in the space between the plates? Give your answer in volts/meter. V/m (b) What is the electric force on a 75.0 nC charge located halfway between the two plates? Give your answer in micronewtons. μN
Two large circular metal plates are parallel and nearly touching, only 3.5 mm apart. The two plates are connected to the opposite terminals of a 9.0 V battery. (a) What is the average electric field strength in the space between the plates? Give your answer in volts/meter. (b) What is the electric force on a 25.0 nC charge located halfway between the two plates? Give your answer in micronewtons.
QUESTION 2 Two ropes, with tensions T1- 5 N and T2 - 2.5 N, pull on a pulley as shown in the figure T1 T. 2 The pulley is a uniformly dense cylinder with a radius of 5 cm and a mass of 2 kg. The pulley rotates around a frictionless axle that passes through its center. The pulley is initially at rest, but after the tensions are applied begins to rotate. What is the net work (in J) done...

Question 4 (force vectors) Two people are pulling on a crate through two ropes. Person A is on the left pulling toward the left with a force of 50 N at 45° and person B is on the right pulling toward the right at an angle of 30°. Here is what the situation looks like from above. The resulting acceleration of the crate is at 0°. acceleration direction person B F 30° person A 50 N 45° 130% 45% crate...
